He continued, that "I'm Your Angel" "sells big at the bridge, where the instrumentation drops and Kelly and Dion harmonize in a gorgeous minor key – it truly makes the song".

[7] A mixed review came from EW editor Chris Willman: "Dion's earnest take on Vietnam-era Lennon is howler No.

[8] David Browne of EW wrote: "By the time R. winds up — with "I Believe I Can Fly" and "I'm Your Angel," a belt-by-numbers duet with Dion — Kelly has realized his crossover dream".

[14][15] The single was nominated at the 41st Annual Grammy Awards for Best Pop Collaboration with Vocals,[16] but lost to "I Still Have That Other Girl", by Elvis Costello and Burt Bacharach.

On 14 January 2019, following Lady Gaga’s removal of "Do What U Want", Dion, through her management, had the song on her own releases and its video pulled from streaming services due to renewed allegations of sexual misconduct and abuse against R.
